Serial nmnasailalliahm itmwy ammo: of a sleeve or supply member D which is it known that we, FRANK Kenmo- KlAMlllflDd Fnmnmcx Konmoxmurn, citizens of the United "States, residing at Omeinnati, =in-the county of Hamilton and State of Ohio,xhsve invented :certa'm new and useful Improvements in Sprayin -Nozzles, of

which the'followingiis a cation.

0m invention relates to improvements in spraying nozzles.

One of its objects is :to provide a nozzle adapted to spray white-wash and chemicals of a -'itt'.y'=and corrosivenatum without; materi injury to the nozzle therefi om.

Another object isto provide an improved nozzle by means'of which the character of the spray may be readily changed.

.knother objmt is to provide a simple and reliable device for the above purpose.

It further consists in certain details of form, combination and arrangement, all of which will be more inlly set forth in the descfiipticm of the accompanying drawings, in w ich:

1 is a side elevation of our improved spraying mzale delivering a jet of spray adapted to reach a considerable distance from the nozzle. Fig. 2 is a similar view showing the nozzle :deliverin a finer s ray adapted to cover a large sur ace at a s orter distance from the nozzle. Fig. 3 is an enlarged central vertical section through the nozz e arranged to deliver the character of s ray indicated in Fig. 1. Fig. 4 is a similiir view showing the arrangement of the nozzle parts to deliver the character of spray indicated in Fig. 2. Fi 5 is a perspective view of the central plug etached. Fig. 6 is a tog plan view of the plug as shown in Fig. 5. 1g. 7 is a bottom plan view of the plug as shown in Fig. 5. ig. 8 is a section on line w w of Fig. 6.

In the accompanying drawings, A represents a flexible hose supplying the material .ing material issuing from .the

threaded at one end to the end of pipe C andatthe. other end is internally threaded to receive one'endof the plug E. An orifice or cap member F is internally threaded at one end to receive the opposite end of the plug E, the opposite end of the cap member forming a conical chamber f and terminating in a small exit orifice f through which the material to be sprayed issues. A acking washer H is interposed between the aliutting ends of members D and F to seal the joint and prevent leakage, said washer being preferabl of leather or rubber. The plu member serves to unite the members F, being partly threaded into each, and is adapted to be reversed or turned end for end to change the nature of the s ra The spraying material passes thrtlug t e plug by means of a passage K formed by boring two holes la is from opposite ends of the lug so as to intersect. The hole is bored parallel with the longitudinal axis ofthe plug and at one side of the axis, and the hole In is bored at one side of the-center of the plug and at an angle to the face of the plug so that the two holes produce :a bent or angular passage K through the bcdy'of the plug.

When the Iplug is arranged relative to the members D as indicated in Fig. 3, a comparatively long compact jet such as indicated in Fig. 1 is produced,which finally breaks into a fine spray. When the plug is arranged as indicated in Fig. 4, the sprayplassage k is given a rotary motion within 0 amber if by the direction of the current issuing rom passage k which causes a widely diffused and very fine spray to issue from the orifice f. A seat a in one end of the plug E for a screw-driver enables the plug to be conveniently inserted and detached.

The arran ement of the angular passage K through t e body of .the plug prevents any wear from gritt or corrosive substances on the thr'eade parts of the nozzle, and the arrangement herein illustrated and described reduces the wear at the orifice f to a minimum, and provides a ready and convenient means for renewal of the parts when worn.

We referably provide a polygonal exterior or the member F to serve as a wrench seat if required to unite or separate the nozzle parts. The member D may also be pro cylin vided With-a olygonal exterior as indicated in Fi s. 1 an 2, or may be grovidedlwith a 'cal'exterior if desire The mechanism .herein illustrated and described is capable of considerable modifica- 1 tion without departing from the principleof our invention. e

- Having" described our invention, what-we "claim is:
